I read on here where someone wasn't getting heat in the passenger compartment and they ran a test to see what codes came up, the code he
got was something about the blend door. Was wondering how to run the test as I have no heat.
Empty the glove box.
Pinch the sides toward the center and the door should open way down.
Inside and to the left and down you should see the blend door motor.
See pic, but yours should be white for manual control.
Key on, not started.
Turn your control to either side and watch the shaft.
Shaft is shown at the top of the motor, and see square hole.
As you trun your temp knob side to side, the shaft should follow.
It is slow to follow, maybe 12 seconds from one side to the other.
Turns 90 degrees.
If it does not move, your most likely cause is bad motor.
